We look at the division of 75928564 by 394 
The aim is to understand the frequency of 394 in 75928564.

Advancing to step 1:
7 divided by 394 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 394

Moving on to step 2:
The number 394 fits into 75 0 times, leaving a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 75, we end up with 75.
Fetch the next digit (9) from the dividend, attach it to 75 and continue: 759 / 394

Moving on to step 3:
If we divide 759 by 394, we get 1 and a remainder of 365.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 394 from 759 and we're left with 365.
Grab the next digit (2) from the dividend, add it to 365, then carry on: 3652 / 394

Moving on to step 4:
3652 divided by 394 is 9 with a remainder of 106.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtract 3546 from 3652 to get 106.
Take the next digit (8) from the dividend and append it to 106, then repeat: 1068 / 394

Let's proceed to step 5:
When dividing 1068 by 394, we get 2 with a remainder of 280.
Put 2 as the next digit of the answer. 
Result so far: 192.0
The remainder is 280 after subtracting 788 from 1068.
Grab the next digit (5) from the dividend, add it to 280, then carry on: 2805 / 394

On to step 6:
The number 394 fits into 2805 7 times, leaving a remainder of 47.
The next digit of our result is 7. 
Result so far: 1927.0
The remainder is 47 after subtracting 2758 from 2805.
Bring next digit (6) of the dividend behind the 47 and repeat the process: 476 / 394

On to step 7:
The number 394 fits into 476 1 times, leaving a remainder of 82.
The number 1 becomes the next digit in our result. 
Result so far: 19271.0
Subtracting 394 from 476 leaves us with 82.
Take the next digit (4) from the dividend and append it to 82, then repeat: 824 / 394

Step 8:
If we divide 824 by 394, we get 2 and a remainder of 36.
The next digit of our result is 2. 
Result so far: 192712.0
Subtract 788 from 824 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 9:
394 can be fit into 360 0 times, resulting in a remainder of 360.
Record the quotient 0 as the next digit in the result. 
Result so far: 192712.0
If we take 0 away from 360, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 10:
3600 divided by 394 is 9 with a remainder of 54.
Record the quotient 9 as the next digit in the result. 
Result so far: 192712.09
Subtract 3546 from 3600 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 11:
The number 394 fits into 540 1 times, leaving a remainder of 146.
Put 1 as the next digit of the answer. 
Result so far: 192712.091
Subtracting 394 from 540 leaves us with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Let's proceed to step 12:
When dividing 1460 by 394, we get 3 with a remainder of 278.
Use 3 as the next digit of our solution. 
Result so far: 192712.0913
Subtracting 1182 from 1460 leaves us with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Going ahead to step 13:
394 goes into 2780 7 times with a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 192712.09137
Subtract 2758 from 2780 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 14:
When dividing 220 by 394, we get 0 with a remainder of 220.
The next digit of our result is 0. 
Result so far: 192712.09137
If we subtract 0 from 220, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 15:
The number 394 fits into 2200 5 times, leaving a remainder of 230.
The next digit of our result is 5. 
Result so far: 192712.0913705
Subtracting 1970 from 2200 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 16:
394 can be fit into 2300 5 times, resulting in a remainder of 330.
Put 5 as the next digit of the answer. 
Result so far: 192712.09137055
If we take 1970 away from 2300, we end up with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

The final result is 192712.09137055 with a remainder of 3.3e-07.
